' and tone arm when said sound box is not in playing position.

This object we accomplish in the manner hereinafter set forth, referencebeing had to the accompanying drawings, in which- Figure 1 is a planview of a talking machine showing the casing, the record-carryingturntable, the tone arm, and sound box, and such portion of thebrake-operatlng mechanism as appears upon the outside of the casing; Y

Fig. 2 is a side elevation showing certain of the turntable rotatingdevices, and the way in which the brake acts thereon;

Fig. 3 is a side elevation of the brakeoperating mechanism looking inthe direction of the arrow m, Fig. 2;

Fig. 4 is a plan view of the mechanism shown in Fig. 3;

Fig. 5 is a view similar to Fig. 3, but showing the manner in which thesound box cooperates with the brake-operating mechanism in order tocause the brake to act' Fig. 6 is a side elevation of a modified form ofbrake with its operating mechanism;

Fig. 7 is an end view of the same looking in the direction of the arrowy, Fig. 6

Fig. 8 is a plan view of the same with the parts in the positionsassumed by them when the turntable is rotating, and

Fig. 9 is a similar view showing the parts in the positions assumed bythem when the brake is applied to stop rotation of the turntable.

Referring in the first instance to Fig. 1, the talking machine casing 1is shown, together with the turntable 2, turntable-operating shaft 3,sound box 4, and tone arm 5. The sound box is shown as being rigidlyPatented Sept. 18, 1917.

Serial No. 160,759.

attached to the tone arm in which case the tone arm will be pivoted atits inner end 6 1n such a manner as to be both laterally and verticallymovable and, in the case of a construction of this kind, our improvedbrake mechanism is designed to be actuated by the combined weights ofthe sound box and the tone arm. In cases where the tone arm is capableonly of lateral movement the sound box will be vertically movable withrespect thereto, and in such case our brake mechanism will be actuatedby the weight of the sound box alone.

In Figs. 2 to 5 we have illustrated the preferred form of brakeoperating mechanism and have shown how the brake operates to permit orprevent the rotation of the turntable 2. Referring to Fig. 2, in which,for purposes of clarity, no attempt has been made to illustrate theturntable rotating motor, the turntable shaft 3 is shown as adapted tobearings in upper and lower frames 7 and 8, and projecting through theupper frame 7, through the top casing 1 and carrying the turntable 2 atits upper end.

The shaft 3 is provided at its lower end with a spur wheel 9 through themedium of which rotation is imparted to the shaft from the motor. Theshaft is further provided between the frames 7 and 8 with a Worm wheel10 which meshes with a worm 11 formed on a governor shaft 12 adapted tobearings 13 depending from the upper frame 7. One end of the governor,which is equipped with the usual weights 14, is fastened to the shaft 12and the other end is free to slide thereon and carries a brake disk 15.

Cooperating with the brake disk 15 is a brake pad 16 carried by one arm17 of a bell crank lever mounted in bearings on the upper frame 7. Theother arm 18 of this bell crank lever is provided at its outer end witha spring finger 19 which bears against the lower face of an adjustingscrew 20 which passes through the casing 1. By means of this adjustinvscrew 20 the speed of rotation of the turntable is regulated, as thevertical adjustment of the screw causes the brake pad 16 to bepositioned closer to or farther from the brake disk 15 of the governor.

Passing; vertically through the screw 20, beingr guided thereby and freeto slide therethrough. is n rod Q1 the lower end of which also beursagainst the spring finger 19, the upper end being pivotally connected tothe outer-'end of e lever 22 which is pvotally mounted upon u. stud 23opstanding from u plate 2l fastened to the outer face of the casing l.This lever 2Q is provided Vwith u pocket 25 for the reception of thesound box 4 Whenthe seme is not/in playing'position.

Willen the sound box is in playing position the ports occupy thelposition shown in Figs. 2 and 3, and the brake pod 1G is moved awayfrom the bra-ke disk l5, permittingjr the letter to revolve. Vhen,however. the sound box is removed from playing position end dropped intothe pocket 25 formed inthe lever 22 the weight of the sound box causesthe brake actuating parts to assume the position shown in Figi, 5, therod 2l being pushed down through the speed regulating; screw 20.pushinga down the spring inger 19 and arm 1S of the bell erenk lever undso sivinffing` the nvm 1T of the bell crank lever es to bring the brakepad 1G into Contact with the brake disk l5 of the governor and reventfurtherrotntion of the seme,:tliere by stopping the rotation of theturntable. The spring linger 19 nt the outer end ofthe arm 18 of thebell crank lever serves as a shock absorber in ease the sound. box iseecidentully or carelessly dropped too heavily into the pocket on thelever 22, end pre vents the jar being; passed on to the governormechanism.

lf it is not desired to employ the Weight of the sound box to operatethe brake the operation may be independently accomplished manually bymeans of n rotatable le ver QG pivotully mounted upon the plate 24 (Eig.el). One nrm 27 of the lever 26 is adapted to be grasped by the fingersand the other erm 2S is provided with n Cem 29 which cooperates with a.teil 3) on the lever so that seid lever 2") muy be moved from theposition shown in Fig. 3 to tlmt shown in Fig'. or vice versa, bv Ineensof partial rotation of the lever 26, the movement `of which is limitedby u lug 31 struck up from the plate 24 and in engagement with o notchin the edge of the lever 26.

In Figs. 6 to 9 We have illustrated e modified Vform of brake whichoperetes against the edge of the turntable so es to frictionully preventrotation thereof. In this ldevice e lever 22a provided with the soundbox receiving pocket 25 is pivoted to n` lug 23a npstending from e plate24a and has its lower edge in engagement with n, cam fece 33 formed onone arm of a lever 34 pivoted to the plete 24a. The other erm of thelever 34 carries n brake pad 35 which is adapted to engage directly theedge of the turntable 2. The lever 34 is normally held by means of aspring' 36 so that the broke purl 35 is free from Contact with the edgeof the turntable Vbut when Vthe -lever 2Q is acted upon by the Weight ofthe sound box it is pushed down and the ucti'onrnof its lower edge uponthe cam face 33 serves to swing the lever 34 labout its pivot so :is tobring the brake pod 35 into Contact with the edge of the 'tu'rntzble'9.therebv preventingrr further frotation of the seme.
